Grim news out of the Netherlands today as the AFP reports that Greg Halman, an outfielder for the Seattle Mariners, was stabbed to death. Police were called to an apartment in the Dutch city of Rotterdam early Monday morning, where they found Halman’s body with multiple stab wounds.

“A 24-year-old man was found dead and the brother of the victim has been arrested and is being questioned,” the Rotterdam police spokeswoman, Patricia Wessels, told the AFP, confirming that man was the Dutch-born Halman. She went on the recount that an investigation was ongoing and that Halman’s girlfriend had been the one to call the police.

Halman had only been playing in the Major League for a little over a year, however, according to CNN, he’d been a serious player for years. He was once a member of the Royal Baseball and Softball Union of the Netherlands, when he’d played for an amatuer team as a teenager in his hometown Haarlem, just outside Amsterdam.

Sadder still, Halman’s younger brother was arrested after the body was found. There’s no word yet on whether he’s been formally charged.
